SLIDING-DOOR FASTENER.

SPECIFICATION forming part of Letters :Patent No. 622,167, dated March 28, 1899.

Application iiled April 26, 1898. Serial No. 678,842. (No model.)

To all whom t may concern:

Be it known that I, GUSTAF LIBERT BEEN- sTIEENA, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Fastening Devices for Sliding Doors, of which the following is a speciiication.

This invention relates to improvements in fastening devicesfor sliding doors; and it has for its object to facilitate the opening and closing of the door, and when used on steam or street cars or on board vessels it serves to prevent rattling and the accidental opening of the door, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein- Figure l represents a front elevation of a sliding door provided with my improved fastening device. Fig. 2 represents a rear elevation of the same. Fig. 3 represents an enlarged horizontal section on the line 3 3, shown in Fig l; and Fig. 4 represents an enlarged vertical section on the line 4 4, also shown in Fig. l. l

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

A represents a sliding door, and B represents the hollow door-casing into which the door is moved when it is being opened', as is common in sliding-door devices.

O represents the opposite door-casing, which serves as a stop against the door when closed.

To one side of the door is preferably secured a metal plate D, provided with ears or projections d d, in which is journaled a vertical bar E, to which the handle E is attached or made integral with it, as shown. On the vinterior of the plate D is pivoted at f the latch F, the free end of which is hooked, as shown at f, and adapted to interlock with a plate or projection C', secured to the casing O, as shown in Fig. 3.

G is a spring interposed between the latch F and the door A, as shown in Fig. 3, and it serves to hold the hooked end interlocked with the projection C when the .door is closed.

bar E is made a bent lever or cam projection e, the free end of which passes through a perforation D in the plate D and lies in contact with the latch F, as shown in Figs. 2 and 3.

To open the door from the side where the handle E is located, it is only necessary to take hold of such handle and pull it in the direction of arrow shown thereon in Fig. 3, causing the lever e to depress the latch F against the spring G sufficiently to disengage said latch from the projection O, thus allowing the door to be freely opened. To close the door, the operator takes hold of the handle E and moves it in an opposite direction to that shown by the arrow, causing the rockerbar E to be brought in contact with the doorplate D, thus preventing the handle from turning during the closing operation of the door. As the door reaches its closed position the yielding latch F is caused to be interlocked with the projection C', as shown in Fig. 3. On the opposite side of the door is pivoted to brackets h h-a vertical bar H, to which is attached the handle II'. Preferably integral with the rocking bar H is made a lever or projection 71,', to which is pivoted a link I, the inner end of which is pivoted to the latch F, as shown in Fig.Y 3. If it is desired to open the sliding door from the side on which the handle H is located, it is only necessary to take hold of said handle and.A

move it in the direction of the arrow shown thereon in Fig. 3, causing said handle to be rocked sufficiently to cause the latch F to be disconnected from the proj eotion O' and allow-- ing the door to be opened by further pressure on said handle H in the direction of the arrow shown in Fig. 3.

In closing the door the operator takes hold of the handle H and moves it in a direction opposite to that shown by the arrow in Fig. 3, and during such closing motion the bar II or its lever h serves as a stop to prevent the handle H from being rocked. As the door reaches its closed position it is caused to be locked by the yielding hooked latch Fand projection C the same as if actuated from the opposite side.

It will thus be seen that the door can be closed and opened from either side and locked in closed position simply by manipulating a pivoted handle arranged on opposite sides of the sliding door without the need of inde- IOO pendent locking,Y devices, making the invention particularly well adapted for sliding doors on street or railway cars, &c., where the Vehicle is exposed to jars tending to open the door when not provided with a locking device.

Having thus fully described the nature, eonstruction, and operation of my invention, I wish to secu re by Letters Patent and claiml. The combination'with a sliding door, its easing, and a locking projection on said casing, of a pivotally-lnounted spring-pressed latch on said door adapted to engage said projection, a pair of pivotally-monnted handles, laterally-extending arms or levers on said handles, one ofv which is adaptedto engage said latch,V and a link connecting the arm on the other of said levers with said latch, substantially as described.

2. The combination with a sliding` door, its

casing, and a locking projection on said casin g, of a horizon tally-movable, spring-pressed latch,.pivotally mounted in a socket in said door, pivotally-mounted handles on opposite sides of the door, each adapted to swing in a horizontal plane and each provided with'a laterally-extending arm or lever, one of said arms or levers projecting through a slot in the door and engaging said latch and the other connected to said latch by a link which extends through an opening in the door7 substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
